anderson awning window operator

Question

Is there a difference between operator 39-099 and 39-343. I bought one with the adaptor plate, and I do not need to use the plate. After installing the operator, I cannot close the window completely, the arm of the operator is hitting the window sill. Any suggestion?

Thanks for posting. Are you sure you don't need to use the adapter plate? You might want to give it a try just in case. It may give your operator enough height so that the arm doesn't bump against the sill.

The 39-343 fits Andersen's Perma-Shield Enhanced awning windows from 1995 to 1998, while the 39-099 fits Perma-Sheild Improved E-Z Awning windows 1999 to present.
